IssueTracker

Please provide a way to retrieve the URL for the YouTube-specific emojis. I suggest two elements here:

1. Add some kind of emoji-identification data to the liveChatMessage values returned in the LiveChatMessages response list. My personal suggestion would be an array of location, length, and emojiId values.

   GET https://www.googleapis.com/youtube/v3/liveChat/messages
   ...
   items: [
     {
       "kind": "youtube#liveChatMessage",
       "snippet": {
         "type": "textMessageEvent",
         "displayMessage": ":face-blue-smiling: hello friends :person-turqouise-waving:",
         "textMessageDetails": {
           "messageText": ":face-blue-smiling: hello friends :person-turqouise-waving:"
         },
         "emojiList": [
           "0+19:UCkszU2WH9gy1mb0dV-11UJg/KsIfY6LzFoLM6AKanYDQAg",
           "34+25:UCkszU2WH9gy1mb0dV-11UJg/ssIfY7OFG5OykQOpn4CQCw"
         ]
       }
     },
     ...
   ],
   ...
   

2. Add an emoji lookup method in one of two forms:

   • Pass an emojiId and receive a URL

     GET https://www.googleapis.com/youtube/v3/liveChat/emoji?id=UCkszU2WH9gy1mb0dV-11UJg/hf90Xv-jHeOR8gSxxrToBA
     [
       {
         "url": "https://yt3.ggpht.com/WxLUGtJzyLd4dcGaWnmcQnw9lTu9BW3_pEuCp6kcM2pxF5p5J28PvcYIXWh6uCm78LxGJVGn9g=w24-h24-c-k-nd",
         "width": 24,
         "height": 24
       },
       {
         "url": "https://yt3.ggpht.com/WxLUGtJzyLd4dcGaWnmcQnw9lTu9BW3_pEuCp6kcM2pxF5p5J28PvcYIXWh6uCm78LxGJVGn9g=w48-h48-c-k-nd",
         "width": 48,
         "height": 48
       }
     ]
     

   • Request an emoji list that takes a liveChatId parameter and returns a list of all global YouTube-specific and custom uploaded emojis for the specified channel.

     GET https://www.googleapis.com/youtube/v3/liveChat/emojis?liveChatId=[REDACTED]
     [
       {
         "emojiId": "UCkszU2WH9gy1mb0dV-11UJg/CIW60IPp_dYCFcuqTgodEu4IlQ",
         "shortcuts": [
           ":yt:"
         ],
         "searchTerms": [
           "yt"
         ],
         "image": {
           "thumbnails": [
             {
               "url": "https://yt3.ggpht.com/m6yqTzfmHlsoKKEZRSZCkqf6cGSeHtStY4rIeeXLAk4N9GY_yw3dizdZoxTrjLhlY4r_rkz3GA=w24-h24-c-k-nd",
               "width": 24,
               "height": 24
             },
             {
               "url": "https://yt3.ggpht.com/m6yqTzfmHlsoKKEZRSZCkqf6cGSeHtStY4rIeeXLAk4N9GY_yw3dizdZoxTrjLhlY4r_rkz3GA=w48-h48-c-k-nd",
               "width": 48,
               "height": 48
             }
           ],
           "accessibility": {
             "accessibilityData": {
               "label": "yt"
             }
           }
         }
       },
       ...
     ]
     

   The second lookup option would greatly reduce the number of API requests required compared to the first, so it's probably the ideal choice.

While the lookup method alone would be functional, the added liveChatMessage data would allow software to easily detect not only the emojis themselves, but if a user has access to an uploaded (member) emoji.
